Notes
The Hollow King Set is the tenth special themed set to be released.
The set confers additional stat bonuses when at least two of the items are worn together. Wearing the full set transforms the necromancer player into a 16x16 sprite and changes the weapon’s shot.
In addition to the stat bonuses this set provides, its staff boasts 3 shots instead of two at 75% fire rate, and the skull forgoes any healing, granting 
Damaging for 3 seconds instead. The damage of the skull is unaffected by Wismod.
A necromancer with WC tops and a Ring of the Pyramid would have 860 HP, 460 MP, 83 ATT, 42 DEF, 50 SPD, 60 DEX, 40 VIT, 81 WIS, making for a DPS of 2316-1512 (0-60 DEF). This set instead offers 2915-1987 DPS without ability use, going as high as 3644-2716 while under the effect of Damaging, which is not sustainable due to the high ability cost compared to the short Damaging time, but still allows for phenomenal damage over short periods of time. This set swaps a few points of 6 WIS for 10 VIT, beneficial since Wismod does not affect ability damage, which stays at a flat and strong 400, also ignoring up to 400 DEF. Unfortunately, with great power comes great fragility: not only does the necromancer lose 90 HP, he most significantly loses the healing power of its skull, making this set’s wearer closer to a wizard than a mundane necromancer. Therefore, wear this set only if you are comfortable to go without healing, or have a swapout skull on hand.
Like the Phylactery Mystic Set, the descriptions of all items in the Hollow King Set are unorthodox and in first-person narration, the Toga Picta and the Interregnum failing to even mention their respective items. However, unlike the Phylactery Set, all four descriptions are parts of a unified narrative1.
The story is told by a staff-wielding2 individual who dies in a duel with a “great spectre” and “join(s) him in undeath”3.
